A body has a uniform motion, if if thavels equal distances in equal intervals of time. no mattor how small these time intervals mav be example, a car running at constant speed of say, $10$ metres per second, will cover equal distances of $10$ metres, every second, so its motion will be uniform. The distance$-$time graph for uniform motion is a straight line.
